Product Detail Information


1. VITZROTECH VDS(V.I Disconnecting Switches) INTRODUCE


  ● VITZROTECH V.I Disconnecting Switch is a disconnecting switch used at M.TR 

      secondary 25.8kV bus rear section of 154kV/345kV substation (outdoor steel structure) 

      applied with a Rotary Spring Switch mode (3-phase integrated operation, single-tank 

      type) which is superior in terms of opening and closing operations. A maintenance-free 

      VI is applied to the disconnecting part and the insulating part of the disconnecting part is  

      accepted in the SF6 tank to prevent the failures in the substation (outdoor steel 

      structure) and system in advance and to enhance the operating efficiency and  

      reliability of the substation. In addition, it is an optimal product developed with a  

      structure that enables an automatic operation of the steel-structured substations. 


   Safety _ It uses a vacuum interrupter to improve the performance of the existing  

                    disconnecting switch. 

    - The vacuum interrupter is applied to the internal disconnecting part to enhance the load switching and 

       insulating capability. 

    - It overcomes the limits of the existing insulation mode and adopted a stable structure with an easy  

       maintenance and inspection. 

    - It is designed in a single-body type cabinet to prevent the gas leak and to improve the stability.  


  Convenience _ By adopting an exclusive control box, it is easier to check the 

                               information on hot-line state. 

    - By using the exclusive control box, it is easier to check the information on control and state of the  

       disconnecting switch. 

    - It is possible to check the disconnecting switch state (Open/Close, Lock/Unlock) and hot-line statefor  

       each phase. 

    - Certificate IEC62271-102 


  ● Its electrical performance is excellent by adopting the magnetic materials with good  

      freezing and thermal capability. 

    - It is equipped with the impulse insulation strength and all the bonded parts are treated to prevent gas
